crispyke35 Posted February 15, 2009 Report Share Posted February 15, 2009 Hi all i have a spare 4k flywheel wanting to know how light i could get it machined down. wanting to get an idea what is a good weight that people have used and what it did for making revs but still being drivable on the roads. Any info of what others have done and how it went would be great. Cheers Quote Link to comment Share on other sites More sharing options...

Wanting to find out what people are running and how this affected the engine. Quote Link to comment Share on other sites More sharing options...
trav_555 Posted February 16, 2009 Report Share Posted February 16, 2009 ive heard you don't go faster you go quicker, also it is more dangerous, maybe it would be worth looking into an aftermarket pre lightened flywheel? as there designed to take the stress, where as a machined stock one is 26+ years old and meant to be full weight you would find a difference no matter the weight you lightened it to sorry i can't be anymore help Travis Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted February 16, 2009 Report Share Posted February 16, 2009 I made ours 6kg, cost $100- easy to drive with but I can't tell how much quicker as it was an auto and its MUCH quicker with a manual, the flywheel being part of that. When I fitted a lightweight flywheel to my Altezza I was surprised at how much quicker it was in first and second, right from the time I picked it up. That went from 14kg down to 7kg, so it was very different. Quote Link to comment Share on other sites More sharing options...

Thanks guys by the sound of it the old flywheel may be a bit risky to machine down to much. might leave that for a bit longer before i do anything. I'll have a look around for an aftermarket one like you suggested travis. don't want to spend to much so i'll see what happens.

Cheers Jacob aftermarket lightened flywheel for a K engine will either be coming from japan (or NZ if you're lucky), will be secondhand and anywhere from $400 to $1400 outright + shipping (from all the research i've done on them) yahoo auctions is where i've found them coming up the most.
